MINE-cnn WHEEL.

nummnea :number a, ma. semi no. 804,410. l

To all whom it may concern:

. Be it known that I, .WILLIAM H. Bruins, a citizen of the United States, residing at Barnesville, in the county of Belmont and State of Ohio, have invented certain new and useful .Improvements in Mine- Car Wheels, and I hereby declare that the following 1s a full, clear, and exact description thereof, reference being had tothe accompanying drawings, which form part of this specification. v

This invention is a novel im rovement in so-called mine car wheels, an its object is to provide a wheel4 with.v self-contained roller bearings vupon the axle, and which can be readily attached' to and detached from` the axle, and any-broken parts can be v easily and cheaply replaced; andin which longitudinal thrust of they wheel on the axle or axle against the wheel will be amply rovided for, and the bearings will be t orou hly lubricated.

. will explain the invention with referenceto thefaccompanying drawings which illustrate practical embodiments of the invention, andin which- -Figure 1 is a front elevation'of the present preferred form of wheel. Fig. 2 is a vertical section on line 22, Fig. 1. Fig. 3

and is shown as a s oke wheel.

is a view similar to Fig. 2 showing a modi-y tied embodiment of the invention.

The wheel l may be a web or spoke whee It has a I' hub lthe bore of w ich is of larger diameter than the axle 9. In the construction shown in Fig. 1 the outer end. of the hub is closed by a ca 1" preferably'formed integral with the ub, and the front portion 1 of the bore of the hub is of smaller diameter than the rear portion 1l thereof; an annular shoulder' 1e being formed in the hub at the junction of the rtions 1, 1". The axle 9 extends axially mtothe hub but its outer end does not contact with the inner wall of cap plate 1; and .to prevent suchl contact the axle 9 is provided with an annular thrust collar 9l which when the wheel isV in )osition on the axle lies about in the median line of the hub; `and between this fiange 9 and the annular shoulder 1 is interposed an annular thrust plate 2 by which the inward thrust of the wheel, or the outward thrust of the axle is transmitted from the wheel to the collar 9% Within the inner portion 1 of the bore of the hub is fitted a removable annular bushmg 4 which corresponds in external diameter to the internal diameter of the portion 1f of the bore of the hub; and its internal diameter is greater than that of the axle 9. This bushin 4 has an outer end late 4 preferably ormed integral therewlth and a ertured for the passage of the axle 9, as s own. The bushing 4 also preferably has a radially projecting flange 4b which is fitted against the inner end of the hub, and said flange may be provided with perforated ears 4"* that'may be engaged by bolts o which transfix said ears and correspondmg perforated portions 1f of the hub, and

said boltsare secured by nuts 5a or otherl suitable means, so as to rigidly fasten the bushing 4 to the hub. f

In practice in order to enable the bushing 4 to be made in one solid casting the shaft can be divided longitudinally or made in two sections so that the bushing 4 can be slipped onto the shaft 9 from the inside of the flange 9*. An annular thrust plate 2a is interposed between the ange 9'IL and the inner end of the bushing llso as to take up the outward thrust of the Wheel, or. the inward thrust of the axle on the wheel; the ange 9 being interposed between the thrust plates 2, 2B. l

Surrounding the axle within the bore l is a series of anti-friction bearings 6 which may be of any suitable type but I preferably use theV so-called Hyatt roller bearings and a similar set of anti-friction bearings 6a are placed between the axle` 9 and the bushing 4 at the inner side of the thrust plate 2. It will be seen that with this construction the lWheel has substantial roller bearingsupon the axle so that friction is obviated; also that ample thrust bearings are provided by the collar 9a on the axle and the thrust plates 2, 2 and the hub. These interior parts may be thoroughly `lubricated `by filling the annular chamber 7 in the hub between the plates 2, QL'With oil; and said chamber communicates'with an oil' reservoir?a at the side of the hub to which oil can beV supplied through an opening closed by a valve 7" of ordinary construction.

In the-construction shown in Fig. 3 the hub is made of the same internal diameter throughout, and in the outer end .of the bmbf-at the outer side of the bearing plate 2 and flange 9 ,-is secured a removable an- Patented Feb. 24,1914.

nular bushing 8, which is constructed sub- ,stantially like the inner bushing 4; such outer bushing 8 beingA provided with a flange 8" and perforated lugs 8 corresponding to the flange 4" and lugs 4 of the bushing 4; and the bolts 5 transx the lugs 4c, 8 and secure both bushings in position; in this construction the outer set of roller bearings 6- are arranged within the bushing 8 just as the inner set of roller bearings 6a are arran ed within the bushing 4; the outer end of t e bushing 8 is preferably closed by an integral imperforate plate 8a.

In the construction shown in Fig. 3 a

larger oil reservoir 7X is shown which mayl be formed by inclosing a space between two adjacent spokes of the wheel. With this 1 construction the outer bushing can be re-l moved Without taking the wheel off the axle.

What I claim is: Q

1. In combination, an axle having a thrust collar, a Wheel having a hub bored to permit thev entrance of said collar, a bushing sur-l .rounding the shaft within the inner end of said hub, and anti-friction bearings within the hub and surrounding said shaft at opposite sides of said collar.

2. In combination, an axle having a thrust "follar, a wheel having a hub bored to permit the entrance of said collar, a bushing surrounding the shaft Within the inner end of said hub, and annular thrust plates Within the'bub at opposite sides of said collar.

3. In combination, an axle having a thrust collar, a wheel having a hub bored to permit 'the entrance of said collar, a bushing surrounding the shaft within the inner end of said hub, annular thrust plates within the hub at opposite sides of said collar, and

A 40 roller bearings within the hub and bushing' and surrounding said shaft at opposite sides of said collar.

4. In combination, .m axle having a collar adjacent its end, a wheel having a hub bored to fit over said collar, means engaging said collar to prevent inward` movement of the Wheel on the axle, and a removable bushing in the hul',- at the inner side of the collar to prevent outward movement of the wheel onA posite sides of the collar and thrust plates.-

6. In combination, an axle having a. thrust collar, a wheel having a hub provided with a bore of larger diameterthan said collar, annular thrust plates on said axle at oppo. site sides of said c ollar and within the bore of the hub, sets of roller bearings within the hub and surrounding the shaft at opposite sides of the collar; and a removable bushing secured to the inner end Aof the hub and interposed between the adjacent roller bearv ings and inner wall of the hub.

7. In combination withl a wheel having a hub, an axle having a thrust collar within Y the hub; removable cylindrie bushings fitted on the sha-ft and withinthe hub at opposite sides of the thrust collar, means for detach' ably attaching the bushings to the hub; and roller bearings interposed between the shaft and the said bushings.

8. Inc'ombination with a wheel having a hub, an oil reservoir communicating with the bore of the hub; an axle having a thrust collar on its end within the hub; removable cylindric bushings fitted on the shaft within the hub, at opposite sides of the collar, and means for detachably attaching the bushings to the hub; thrust plates interposed between the collar and the said bushings; and anti-friction bearings interposed between the shaft and the bearings.

In testimony that I claim the foregoing as my own, I affix my signature in presence of two witnesses.
